<p>The module is fitted with a front plate and a pull handle, insertable into a module support whose transverse rails have each a T-shaped groove, engageable by locking members. The locking device is formed by a latching hook (27), penetrating the front plate (1) of the module (25). The hook forms a part of the pull handle (2) and is fitted with a delocking arm (12), movable w.r.t. the handle. Pref. the hook and delocking arm are parts of a two-arm lever, coupled integrally by a flexible chip (6) mounted at the lever pivot point. Between the handle and the delocking arm may be incorporated a compression spring. The locking flank of the hook may be inclined at a sharp angle in the direction of the spring force, and may be stepped in shape.</p> |
